Math problem

[kabott]

Hi, im an arts guy, math was always my Aquiles heel, i been trying to find a way to input a percentage i wanna display between 2 values, i been looking around, googled it but cant find the right formula

Basically i have "Value X" & "Value Y", and i want to, manually via parameters display the 30% increase between those two numbers ..

double Calc= ( ? formula ?? PercentageInput ? );

help please

Hello kabott,

If I'm understanding correctly, you are trying to find a result of a 30% increase in two numbers -- is that correct? You can accomplish this by multiplying the value by 1.30. For example:

double Calc = xValue * 1.30;

Or, if you're looking to calculate the total of two numbers, both of which increased by 30%, you can use parenthesis to separate the multiplication from the addition, like so:

double Calc = (xValue * 1.30) + (yValue * 1.30);

Alternatively, if you are trying to find the percentage change between two numbers, you can use the formula for percentage change, like so:

double Calc = ((newValue - oldValue) / oldValue) * 100;

Please let me know if I can assist further.

Hi Davel, im not sure which one is it, i have 2 numbers

x ---------------- example 1.568 (being the 100%)


y----------------- example 1.250 (being the 0%)

and by imputing in parameters example "30"

i want a percentage line to show what the 30% is between those two numbers, so



x ---------------- example 1.568 (being the 100%)

p------------------ ?? (being the 30 %)
y----------------- example 1.250 (being the 0%)


man, i suck at math lol

Hi kabott,

I see what you mean now. We normally do not dive too deep into handling math and logic problems, but one way to do this would be to determine the value equal to 30% of the distance between x and y, then add that value to y, like so:

p = y + ((x-y) * .30);

This thread will remain open to allow other forums members to add their comments, as well.

Please let me know if I can assist further.

Davel gave you the formula. Just want to edit it a little bit, since you want to input "30" instead of "0.3", the formula will be:

p = y + (x - y)*Factor/100

where Factor is your input, such as 30, 20, 40...
(assuming Factor is a "double")

Cheers,
Pi

slippage in stocks

Hello, how to calculate slippage in stocks?

example;

I necestio one action = $ 0.10 As slippage?

Thank you.

Hello Optimuss,

Just to clarify -- are you currently trading live through a broker, or are you using a Sim account? If you are trading live through a broker, there will not be a way to add a set amount of slippage to historical order reporting. The slippage that occurs naturally on live orders can be calculated by comparing your order entry prices to their corresponding fill prices.

If you are using a Sim account, you can set NinjaTrader to mimic a slight delay in transmitting orders and in order fill processing. To do this, click Tools > Options from the Control Center, then click the Simulator tab. In the Simulator tab, change the values in the "Delay Comm" and "Delay Exchange" fields.

Furthermore, if you are using the Strategy Analyzer to backtest an automated trading strategy, you can set a specific amount of slippage to include on each trade.

Please let me know if I can assist further.

Hey, if it is to backtest Strategy.

For 1 action = $ 0.10 to catidad I put in slippage?

Hi Optimuss,

I'll be happy to walk you through the process. However, please note that the slippage must be entered in terms of ticks, so you will not be able to specify a certain monetary value of slippage per trade.

Please use the following steps to add slippage to your strategy backtest results:

- In the Strategy Analyzer, select the instrument that you wish to use for the test, then click the "backtest," "optimize," or "walk forward" button near the top of the window
- In the options window that appears on the right of the Strategy Analyzer, enter a tick value in the "Slippage" field, in the "Historical Fill Processing" section
